Outline of Research at the Start

台湾大学において行うウラン-トリウム年代測定法と東京大学で行う高解像度微量元素分析法を融合させることにより,サンゴ骨格や鍾乳石などの炭酸塩試料から過去の環境を長期間かつ高解像度で復元することを目的とする.氷期・間氷期サイクルや地球温暖化に対し,アジアモンスーン・エルニーニョ・太平洋十年規模振動がどのように応答してきたのかに注目する.また火山噴火が気候変動に及ぼした影響についても評価する.

Outline of Final Research Achievements

The objective of this study is to reconstruct the past environment using stagmalites, bivalves, and other accretionary growth carbonate samples over a long period of time. We measured them with high precision by integrating high-precision dating methods with high-resolution elemental and isotopic analysis methods. Specifically, through joint research with Professor SHEN of National Taiwan University, an authority on uranium-thorium dating of carbonate samples, we determined the ages of stagmalite samples with high precision and conducted high-resolution trace element analysis using a secondary ion mass spectrometer (NanoSIMS). As a result, an environmental cataclysmic event, the eruption of Toba volcano in Sumatra, Indonesia, which occurred about 74,000 years ago, was detected in the East Timorese stagmalite.

Academic Significance and Societal Importance of the Research Achievements

今から約7万4千年前に起きたとされるインドネシア・スマトラ島のトバ火山噴火という環境激変イベントを復元するため,東ティモールの鍾乳石の解析を進めた。国立台湾大学において試料の形成年代をウランートリウム非平衡法により正確に求めた後,噴火を示す部位について東京大学のNanoSIMSを用い, Mg, Sr, Ba, Al, Si, K, Fe, Mnを分析した。その結果,鍾乳洞内の滴下水の酸化還元状態が変化したことを示唆する結果が得られた。破局的噴火が地球環境を激変させる証拠として鍾乳石の研究例を増やすことで、将来の火山防災に役立つ可能性がある。
